Let me read through the problem description carefully. + +The user is reporting that when they try to boot a kernel built for 68020, 68030, or 68060 CPUs using QEMU's m68k virt machine, the kernel doesn't start properly. The issue occurs on Debian Unstable amd64 with QEMU version 9.2.0. They've tried rebuilding the kernel inside a virtual machine using a 68040 CPU, so cross-compilation isn't the problem. + +Each CPU model gets stuck early during boot, showing different outputs like "ABCGH", "ABC", etc., and QEMU uses 100% of a CPU core. The user suspects that the 68020 might need some emulation for the 68851 (which I think is the MMU), but it's not clear if that's the root cause. + +Looking at the possible categories, we have 'mistranslation', 'assembly', 'other', and several others like 'device', 'graphic', etc. The main issue here seems to be related to how QEMU handles different M68K CPU models during kernel boot. + +I'm thinking this might fall under 'hypervisor' since it's about the emulation of a CPU in a virtual machine. Alternatively, it could relate to how the CPU is being emulated by QEMU's M68k support. But I remember that in some cases where specific hardware isn't properly emulated, like MMU or other coprocessors, booting kernels can fail. + +Wait, the user mentioned the 68020 needing 68851 emulation, which is an MMU. So if QEMU's M68k virt machine isn't properly emulating the MMU for those CPUs, that could cause the kernel to not boot correctly. The fact that it works on 68040 suggests that higher models might have better support or don't require as much from the emulation. + +But looking at the categories, 'mistranslation' refers to incorrect mapping in user-mode assembly lowering, which might not be directly related here unless there's an issue with how instructions are being translated. However, the problem seems more about missing hardware emulation (MMU) rather than translation issues. + +Alternatively, since it's a boot issue and possibly tied to CPU features or emulated peripherals, maybe 'peripherals' could apply if the MMU is considered a peripheral device. But I'm not entirely sure about that classification. + +Another angle: the user's kernel config includes all M68K CPUs, so it's expecting QEMU to handle them correctly. If the boot process fails early on with CPU-specific issues, perhaps it's more related to how QEMU emulates the CPU, which falls under 'hypervisor' or 'm68k emulation', but those categories aren't listed. + +Wait, looking back at the possible categories provided: they include 'hypervisor', 'boot', etc. Since the issue is about booting a kernel on different CPUs, and the problem might be in QEMU's CPU emulation, which would tie into hypervisor functions as QEMU acts as a hypervisor when running VMs. + +Alternatively, it could be under 'other' if none of the specific categories fit perfectly, but I think 'hypervisor' is more appropriate because it's about how the virtualization layer (QEMU) handles the CPU models and their respective features during boot. + +So, after considering all this, I think the most fitting category would be 'hypervisor'. +</think> + +hypervisor \ No newline at end of file |
